Cellular and physiological analyses revealed that the apical spikelets in the paab1-1 mutant undergo programmed cell death, accompanied by nuclear DNA fragmentation and accumulation of higher levels of H2O2 and malondialdehyde. ), v.65, n.5, p.502-507, September/October 2008 explained a small portion of the variation on this trait (Oh et al., 2004), discarding the involvement of ma-jor genes in panicle exsertion. Consistent with a function for OsALMT7 as a malate transporter, the panicle of the paab1-1 mutant contained less malate than the wild type, particularly at the apical portions, and injection of malate into the paab1-1 panicle could alleviate the spikelet degeneration phenotype. Molecular cloning revealed that paab1-1 harbors a mutation in OsALMT7, which encodes a putative aluminum-activated malate transporter (OsALMT7) localized to the plasma membrane, and is preferentially expressed in the vascular tissues of developing panicles.
